HYDROCARBON-BURNER.

Application filed April 13, 1918.

To @ZZ ywhom it may concern:

Be it known that I, Louis E. Tnsrnn, a

subject of Great Britain, residing at Sacra- This invention relates to improvements in hydrocarbon burners. rIhe object of the invention is to produce a burner of the type described which will permit the fuel to be gasiiied in such a manner and to such a degree as to eliminate carbon deposits being formed Within the gasifying retort or in the gas pipe and discharge outlet leading therefrom. In most of the present day types of hydrocarbon burners, t 1e retorts are so constructed and so subjected to an intense heat that carbon forms within the retort and then cakes both in the retort and in the outlet pipes and discharge jets leading therefrom. These objectionable features I aim to entirely do away with.

F rom long experimentation I have discovered that in order to produce a perfect burner of the type here claimed, it is necessary to first heat the fuel to the point of vaporization, but not beyond such point, and then allow it to come into contact with plenty of oxygen prior to its being burned. By so heating it the vaporized fuel in the retort retains its chemical composition without breaking up into its elements, thus preventing f'ree carbon from being deposited in the retort and the outlet therefrom.

This I have done in my improved burner and retort, and have eliminated the use of excessive temperature and back pressure in the retort.

characters of reference on the drawings, the numeral 1 designates the support for the vaporizing retort which may be of any desired structure. The vaporizing retort 2 may be of any desired form or dimensions found adaptable according to the use to which the burner is going to be put, and leading` into the same is a fuel supply pipe 3. This pipe 3 may conduct the fuel into the retort either by gravity or forced pressure, as may be desired. The pipe 3 may l have a strainer el at an intermediate point to prevent solid matter from entering the retort.

The fuel passes into the retort 2, and heat is applied to the retort to that degree which will merely cause the fuel therein to vaporize. The rising vapors pass through a relatively large bypassy 5 and thence through a central outlet pipe 6 which passes downwardly through the retort 2 and is provided with a relatively large outlet nozzle 7 A tapered needle valve 8 controls the passageway through the nozzle 7. This needle valve 8 has a shank 9 movable through a guide 10. On the lower end of the shank 9 is a ball 11 which" engages a tapered valve stem 12 having an operating handle 13. Bn operating` the handle 13, the position of tie needle valve 8 may be fixed.

At the base of the needle valve S, at a considerable distance from the discharge nozzle 7 is a burner plate 14. The vapors passing through the nozzle 7 discharge downwardly and strike the plate 14.-. The force of striking this plate 14 causes them to disseminate into the surrounding atmosphere where they are ignited by the flames of the burner.

As the fuel vapor passes out through the nozzle 7 it comes into immediate contact with a liberal supply of air, the atoms of carbon in the fuel then uniting with the oxygen of the air prior toignition. This forms as perfect a burning gas as can be produced in this type of device.

To gain the initial heat for the burner, an asbestos torch may be used or a small quantity of fuel may be placed on the plate lfl and ignited. As soon as the gas is generated, however, then the burner is self sustaining.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is 1. A hydrocarbon burner comprising a burner, a liquid fuel retort positioned to be subjected to the heat of the burner, and a passageway leading from the top of the retort and passing over said top and then down through the retort and terminating below the same, whereby the fuel vapors generated in the retort will discharge onto the burner before being subjected to any heat greater than the heat ol2 the liquid fnelin the retort.

2. A hydrocarbon burner comprising a retort, a nozzle arranged to discharge doWn- Wardly from the under side of the retort, means leadino from the top of the retort to the nozzle W iereby the vapor from the retort may pass freely to the nozzle, a burner plate spaced below the discharge nozzle whereby such vapor will be forced from the nozzle against the plate and be then disseminated from the plate prior to combustion, and a needle valve controlling the discharge nozzle, the plate being movable in the same relation as the needle valve.

3. A hydrocarbon burner comprising a retort, a central pipe projecting through the retort and having a lower discharge opening, the retort having a bypass at its upper end communicating With such pipe, a needle valve controlling the discharge opening, and a burner plate fixed to and movable with the needle valve.

In testimony whereof I affix my signature in presence of tWo Witnesses.
